SYRACUSE, N.Y. -- The Syracuse school board will be asked to cut $8 million from the 2012-2013 budget it passed just two weeks ago, a move that would add 35 layoffs to the 150 job cuts already planned for next year.

The board will hold a special meeting at 5:30 p.m. Thursday to consider the additional cuts, Superintendent Sharon Contreras told city councilors at a budget meeting tonight.

School officials said they decided to reduce their freshly minted spending plan after learning that the $366 million budget passed April 18 would require borrowing more money than the district could pay back in one year. Contreras is now recommending a $358 million budget.

“What we decided, to keep the problem from becoming worse year after year, was to make more reductions this year,” Contreras said.

The district gained a more detailed understanding of its borrowing options during recent meetings with underwriters, which spurred the reassessment, said Suzanne Slack, chief financial officer.

If the amended budget passes, the district would cut 185 jobs — 100 through attrition and 85 through layoffs. Following the school board’s vote, the city council will vote on the school budget next week as part of the overall city budget.
